摘要
针对天文望远镜系统自身的焦散特性以及成像过程中高斯白噪声的影响,依据对透镜系统点扩散函数的先验知识,运用维纳滤波方法对退化的天文图片进行了复原处理。实验表明,这一方法能够对退化天文图片进行有效的复原,同时该处理方法对具有类似问题的光学成像系统的图像处理具有很好的借鉴意义。
In view of the focus scattering characteristics of astronomical telescope systems and the influence of Gauss white noise during the course of imaging, the blurred astronomical images are processed by the method of Wiener filtering, which is based on the known knowledge of the point spread function of a lens system. It is testified that this method can restore the blurred astronomical images effectively and provide a good reference to the image processing of optical imaging systems with a similar problem.
